Appheation filed March 27, 1908. Serial No. 423,779.

To all roll/m 'it may concern:

Be it known that l, CLARENCE L. 'lonLrN- sON, a citizen of the United States, residing at Portland, in the county of lvlultnomah and State of Oregon, have invented new and useful Improvements in YWheels, of which the following is a speeication.

This invention relates to wheels, the object in view being to provide means whereby a tire may be tightened without heating and whereby the spokes may also be tightened or removed and replaced in an easy and practical manner.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement .of parts as herein fully described, illustrated and claimed.

In the accompanying drawing F igure 1 is a diametrical section through a wheel illustrating the novel construction comtemplated in this invention. Fig. 2 is an inside face view of one of the hub sections. Figs. 3 and 4 are respectively plan views of the spoke receiving and spoke clamping sections. Fig. 5 is an end view of the threaded expanding cone looking toward the smaller end thereof. Fig. 6 is a plan view of said cone. Fig. 7 is an end view of the axle box. Fig. 8 is a plan vienT thereof. Fig. 9 is a longitudinal section through one of the gibs. Fig. 10 is an end view of the same. Fig. 11 is a sectional view of one of the threaded shoes. Fig. 12 is an end view thereof.

Referring to the drawings, 1 designates the tire of a w eel, 2 the felly thereof which is made up of sections in the ordinary manner and 3 the spokes of the wheel.

In carrying out the present invention, each spoke is provided at its inner end with a threaded spoke butt one of which is illustrated in detail in Figs. 11 and 12 wherein it will be sepn that said butt comprises an inclined and threaded surface 4t and llanges 5 extending outward from the opposite side thereof thereby leaving a seat 6 for the reception of the correspondingly reduced inner end of the spoke, as seen in Fig. 1. Each spoke is provided with one of the threaded spoke shoes shown in Figs. 11 and 12 and all of the spoke shoes are simultaneously en gaged by a threaded expanding cone 7 which is shown in detail in Figs. 5 and G, the taper of the cone corresponding with the inclinal tion of the threaded surface 4 of the spoke shoes so that as the expanding cone is screwed inward, the spokes are forced outward by reason of the threaded engagement of the cone with the spoke shoes as readily seen in Fig. 1.

'lhe hub comprises a socket or receiving section S which 'lits upon the axle box E), the latter extending through the expanding cone 7 and forming a bearing therefor. 'lhe hub section S is provided with an enlarged disl'-sha] ed portion 1() from which extend lateral tongues 11 between which the inner ends of the spokes are received in the manner indicated in Fig. 1. The hub section S has its outer end recessed and internally shouldered as shown in Fig. 1 while the axle box 9 is provided at the corresponding end with an enlarged head or llange 12 which fits within the recessed outer end of the hub section S and bears against thc internal annular shoulder therein. The other hub section 13 is provided with a dislvshaped portion 111 adapted to bear against the enlarged butt ends of the spokes7 as shown in Fig. 1. and clamp said spokes against the disk-shaped portion of the hub section S, the hub section 1S being held in place by a clamping nut l which is screwed upon the threaded end of the axle box E) as shown in Fig. 1.

'lhe expanding cone 7 is provided at diametrically opposite points with outwardly extending lugs 16 while the hub section 13 is provided with inwardly extending lugs 17, the said lugs of the cone 7 and hub section 13 forming cooperating shoulders whereby when the hub section 1.23 is revolved, a corresponding inovcmei'it is imparted to the expanding cone 7. This provides means for turning the cone and obtaining the expanding action thereof upon the shoes of the spokes, enabling the spokes to be tightened and also enabling the felly sections to bc forced outward in lirm contact with the inner surface of the tire 1.

ln connection with one or more of the points between the ielly sections, l provide gibs, shown in detail in Figs. (J and 1.0, and each gib comprises a curved base 1S, an outwardly projecting' wedge portion 1E) and side flanges 20. ln addition to this the gib comin'ises a mortise 21 adapted to receive a corrcspoinling tenon 22 on the outer end of the spoke, whereby the gib is carried by fir' eaaeee l. A Wheel comprising dered at one end and threaded the other end, hule consisting ol tivo hollow sections embracing the axle box, one section against the shouldered end of the leo:` lint on the bon for pressing the sections toward one another, a riniJ spokes entering sockets in the hub, a inetal shoe the inner end of each spel-e provided -with an inclined threaded inner face, a threaded expanding shoes and cone which enr/ages all of said lugs projecting expanding iorees the sarne outward outward iroin one end or Jhe cone and fo ined integrally 'ruth the latterJ and lugs extending inward from one of the an axle hoi; shoull hul) sections and cooperating i ith the cone lugs7 substantially as described.

f2. A Wheel comprising an axle box7 hub sections mounted Vupon the axle box, one of said sections being relatively fixed and provided with spoke sockets and the other hub section being rotatable and havin@ inwardly extending lugs, spokes mounted in the spoke sockets and having a limited radial inovenient, individual shoes fitted to the inner ends of the several spokes and prevented from longitudinal and lateral inoveinent and having their inner faces inclined and formed with corresponding screw threads, and an enandinff cone slidably mounted upon the box and having screw threads matching and engaging the screw threads of the several individual shoes and provided With lugs projected laterally beyond the larger end thereof to be engaged by and to coperate with the lugs of the rotatable section.

in testimony whereof l affix niy signature in presence of tWo Witnesses.
